Answer:
cot(θ) = 24/7
Step-by-step explanation:
A suitable calculator can answer this nicely.
__
Perhaps you're expected to remember relevant trig identities.
tan(θ)^2 = sec(θ)^2 -1
cot(θ) = 1/tan(θ)
__
cot(θ) = 1/√(sec(θ)^2 -1)
cot(θ) = 1/√((25/24)^2 -1) = 24/√(25^2 -24^2) = 24/√49
cot(θ) = 24/7

Pamela is 5 years younger than Jiri. The sum of their ages is 81. What is Jiri's age?
Answer: Jiri is 43 years old
Step-by-step explanation:
Let x be the age of Pamela, and (x+5) be the age of Jri
Expression
x+(x+5)=81
Expand paranthesis
x+x+5=81
Combine like terms
2x+5=81
Subtract 5 on both sides
2x+5-5=81-5
2x=76
Divide 2 on both sides
2x/2=76/2
x=38
Since we've set Jiri's age as (x+5), we need to substitute the value of x
x+5=38+5=43
Hope this helps!! :)

Kate has some dimes and quarters. If she has 23 coins worth a total of $3.50, how many of each type of coin does she have?
23=d+q, d=23-q
350=10d+25q, using d from above
350=10(23-q)+25q
350=230-10q+25q
120=15q
q=120/15
q=8, and since d=23-q
d=23-8=15
So there are 15 dimes and 8 quarters

Convert the expression (√3)(∜3) to exponential form. Show your work.
Answer:
(3^1/2)(3^1/4)
Step-by-step explanation:
Use the formula
[tex]\sqrt[n]{a} ^x[/tex] = [tex]a^{\frac{x}{n} }[/tex]
[tex]\sqrt{3}[/tex]
a = 3
n = 2, we do not write it because square root is basically replacing it
x = is a period in this case period is 1
[tex]\sqrt[4]{3}[/tex]
a = 3
n = 4
x = 1
Exact Form:
[tex]3^{\frac{3}{4} }[/tex]

A container has 360 gallons ; daniel took 1/3 of water to give to the animals in the ranch; how many gallons of water are left? I NEED IT TO BE EXPLAINED AND I WILL MAKE YOU THE BRAINLIEST
Answer: 240 gallons
Step-by-step explanation:
From the question, we are informed that the container has 360 gallons and that Daniel took 1/3 of water to give to the animals in the ranch. Therefore, the amount of water that Daniel took will be:
= 1/3 × 360
= 120 gallons
Since we have 360 gallons at the beginning and Daniel has taken 120 gallons, the amount of gallons that'll be left will be:
= 360 - 120
= 240 gallons
What is the inverse of f(x) = 2x2 -4?
Need answers asap
Answer:
Step-by-step explanation:
The function doesnt have an inverse. In order for a function to actually have an inverse, it has to pass the horizontal line test. The function above has repeating y-values because of the x^2.
With all this said, you can still find the inverse of the function as long as you restrict the domain (x-values) for the function. So, you cant consider the negative x-values.
First, replace f(x) with y and then switch the x and y variables
[tex]x=2y^2-4[/tex]
Then solve for y by adding 4 to both sides, dividing by 2, and finally taking the square root.
[tex]x+4=2y^2[/tex]
[tex]\frac{x+4}{2} =y^2[/tex]
[tex]\sqrt{\frac{x+4}{2} }=y[/tex]
Solve y^3 =-28 where y is a real number.
Simplify your answer as much as possible.

A large discount store wants to determine the average yearly income of its shoppers. A researcher chooses 100 shoppers at random between 1:00 p.m. and 5:00 p.m. on a Saturday to survey. Identify the population.
A. All shoppers at the discount store between 1:00 p.m. and 5:00 p.m. on this particular Saturday.
B. The 100 surveyed shoppers at the discount store between 1:00 p.m. and 5:00 p.m. on this particular Saturday.
C. All shoppers at the discount store on this particular Saturday.
D. All shoppers at the discount store during a year's time.
E. None of the above.
Answer:
The population is:
D. All shoppers at the discount store during a year's time.
Step-by-step explanation:
Since the discount store wants to determine the average yearly income of its shoppers, the population of interest here is all the shoppers that visit the discount store during a year's time. The population includes all the individual shoppers. However, this number may be too difficult to obtain and work on their data. This is the researcher can choose a sample, calculating its statistics to approximate the population parameters.

Group the digits in pairs, starting with the digit in the units placeThink of the largest number whose square is equal to or just less than the first period. Take this number as the divisor and also as the quotient.Subtract the product of the divisor and the quotient from the first period and bring down the next period to the right of the remainder. the new divisor is obtained by taking two times the quotient and annexing with it a suitable digit which is also taken as the next digit of the quotient, chosen in such a way that the product of the new divisor and this digit is equal to or just less than the new dividend.
